There used to be a difference, but not really any more, I don't think.
Or does print still not allow multiple arguments?...

I use echo, because I'm old, and got in the habit, back when print()
was a function and echo was a language construct, and only echo let
you have as many args with commas as you wanted.
But there's no significant difference, as far as I know.
There is a difference, echo is slightly faster.
code used for benchmark:
<?
$start = microtime(TRUE);
for ($i=0; $i<100000; ++$i) { print "ABC"; }
echo sprintf("With print ($i): %0.3f\n",microtime(TRUE) - $start);
$start = microtime(TRUE);
for ($i=0; $i<100000; ++$i) { echo "ABC"; }
echo sprintf("With echo ($i): %0.3f\n",microtime(TRUE) - $start);
?>
it displays 100000 times ABC, first with the print command, and second
with the echo command. Result:
ABCABCABC<snip>
print (100000): 0.085
ABCABCABC<snip>
echo (100000): 0.076
It's not a lot, but since we are displaying data a lot, (most used
function?) it will make a difference in really big scripts.
